Heat pumps 101: How they work and emissions reductions capabilities
The heating of homes makes up a high share of energy use in countries that have variable and cold climates. In the European Union in 2020, home heating was the main use of energy by households at 62.8% of final energy consumption in the residential sector [1]. Additionally, 15% was used for water heating. At the same time, oil and gas are still the main fuels burned by most local boilers [2].
What is a smart plug? How they save energy & reduce emissions.
A smart plug is a device that fits in between the power socket in your wall and an appliance. They are similar in appearance to power adapters you may have used when traveling. The reason they get the ‘smart’ moniker is because these plugs allow you to control the appliance they’re plugged into remotely, enabling them to function in more environmentally efficient and useful ways.

Reservestrom für Netzausfälle! Der Ford F150 Lightning ist unser Elektroauto des Monats September 2022
Für die Wahl des EV des Monats gibt es zwei Gründe. Erstens: Angesichts der Energiekrise in Europa ist die Netzstabilität in aller Munde. Hier können Elektrofahrzeuge mit Notstromfunktion (V2G, vehicle to grid, oder V2H, vehicle to home) eine wichtige Rolle bei der Stabilisierung des Netzes spielen. Zweitens: Wir haben zwar über E-Fahrzeuge aller Größen und Formen berichtet, aber einen Pickup-Truck hatten wir noch nicht als unser E-Fahrzeug des Monats. Daher stellen wir Ihnen den Ford F150 Lightning vor: ein Pickup-Truck mit großartiger V2H-Unterstützung.
Zero carbon living: what would it cost today?
In order to avoid the most significant impacts from climate change, warming has to be limited to 1.5°-2° Celsius. This could be achieved by decarbonising all human activities, including transport, energy, and food. It requires widespread cooperation to reach zero emissions globally, including the public sector, businesses, but also households. In fact, households are indirectly responsible for about 70% of global emissions.
How green is your electricity? An introduction to carbon intensity
Unless you’ve been living under a rock the past few months, you’ve certainly heard about the expected critical gas and electricity supply situation in Europe towards the winter. Driven by Russia’s reduction of gas deliveries to Europe, the French Nuclear plants struggling with planned and unplanned maintenance, and particularly hot and dry summer, energy prices across Europe have been skyrocketing. These recent developments come on top of an already ongoing transition of our electricity and energy systems to achieve lower CO2 emissions.
Battery swapping! The NIO ES8 is our EV of the month for August 2022
Our EV of the month is noteworthy due to several reasons: it’s large. It’s from China. It features some very innovative technology. Ladies and gentlemen: the NIO ES8.
Wie viel Strom produziert ein Solarmodul? Eine Zusammenfassung der wichtigsten Fakten zur Solarenergie
Mit Solarzellen erzeugter Strom ist ein wesentlicher Bestandteil der Dekarbonisierung unseres Strom- und Energiesystems. Im Gegensatz zur herkömmlichen Stromversorgung, bei der der Strom zentral erzeugt wird und die Haushalte ihn lediglich verbrauchen, können sie nun durch die Installation von Solarzellen zu Energieproduzenten werden. Auf diese Weise können sich die Haushalte autark machen, sich vor hohen Strompreisen schützen und zur Dekarbonisierung unseres Stromsystems beitragen.
Does electric car sharing work? A real-life test.
Shared mobility concepts promise that they reduce the number of vehicles on the road, which is expected to have a positive impact both on the emissions from the production of vehicles, and also less space required for parking lots. While scooters and bikes are hoped to reduce the kilometers driven by cars overall, car sharing would mainly lead to more efficient usage of a smaller fleet of vehicles. If the fleet is electric, emissions from driving would also be reduced significantly.
kWh vs. kW: what's the difference?
With an energy crisis in Europe simultaneous to the transition to a green energy system, energy is truly the topic of the hour. States and consumers alike, are hence urgently looking to reduce their dependence on fossil fuels. When looking into the solutions (electric vehicles, solar, heating with a heat pump, or energy saving), you will sooner or later encounter the units kWh (kilowatt-hour) and kW (kilowatt). However, often these units are confused. Let’s clarify!
The BMW i3, i4, and iX are our EVs of the month in July
For July we have not just a single EV of the month, not even a duo, but a trio of cars! The BMW i3, the BMW i4, and the BMW iX. BMW is an interesting case when it comes to the transition from combustion engines to electric drivetrains. As we’ll show below, BMW in 2013 was a pioneer with the introduction of the i3, but then fell behind and kept lobbying for the combustion engine instead of embracing change.
Ist Videostreaming schlecht für das Klima?

With EV chargers for employees, companies can accelerate zero-carbon transportation
Addressing climate change is a challenge that needs to be tackled at all fronts: countries, cities, and households, but also businesses. Luckily an increasing number of companies commit to net-zero targets. They employ various ways to reach these goals from decarbonising their supply chains to compensation.
Mercedes EQS is our EV of the month for April 2022
Last month our EV of the month was a modern, electric van for Hippies or families. This month we’re addressing a whole other segment: luxury limousines. The idea for this post came about while reading that the Dutch parliament postponed electrification of their fleet, at least partially due to “lack of comfort” when it comes to available EV options.
Is there enough electricity for electric cars?
One of the most common questions (or worries) about electric cars is if there will be enough electricity to power all cars, if they were electric.
Typische CO2-Emissionen von Haushalten und ihre Aufschlüsselung nach Ausgabenkategorien
Wahrscheinlich hast Du schon einmal auf einen der unzähligen CO2-Fußabdruck-Rechner genutzt: Vielleicht ist Dir auch aufgefallen, dass diese in der Regel den CO2-Fußabdruck auf der Basis einer Person (oder “pro Kopf”) berechnen. Und viele Statistiken weisen auch Pro-Kopf-Kennzahlen aus. Die meisten Menschen leben jedoch in einem Haushalt mit zwei oder mehr Personen, in dem einige Ressourcen wie Wohnung (einschließlich Strom, Heizung usw.), Auto (und oft sogar Mahlzeiten) gemeinsam genutzt werden. Das bedeutet, dass für viele von uns der “Haushalt” die relevante Einheit ist, wenn es um das Verständnis von CO2-Emissionen geht.
The VW ID.Buzz is our EV of the month for March 2022
The VW ID.Buzz is likely one of the most anticipated EVs for the year 2022. Ever since the first concept was published, the final design and specs have been eagerly awaited. The reasons for the excitement are manifold.
Three great commuter ebikes for 2022
Commuting by bike allows for combining some exercise and fresh air with the daily necessity of the commute. E-bikes can be particularly useful compared to regular bikes, as they enable commuters to travel further distances, travel faster and help avoid arriving at work exhausted and sweaty. Recent research has also shown that e-bike ownership correlates with a reduction of car usage and public transport usage (albeit no effect on car ownership could be measured). Reducing (ICE) car usage has a direct benefit of burning less oil and with that reducing CO2 emissions.
Ist es umweltfreundlicher, weiterhin einen alten Diesel zu fahren oder ein neues Elektroauto zu kaufen?
Was ist umweltfreundlicher: ein altes Auto mit Diesel-/Benzinantrieb weiterfahren oder ein neues Elektroauto kaufen? Ein neues Elektroauto verbraucht Ressourcen und stößt bei seiner Herstellung CO2 aus, hat aber einen viel geringeren CO2-Ausstoß während der Fahrt. Ein alter Diesel hat seine Produktionsenergie und seine Emissionen bereits “amortisiert”, aber er verbrennt weiterhin fossile Brennstoffe und stößt Treibhausgase aus.
Opportunities in zero-emissions transportation
With about 11% of the total, transportation is one of the key contributors to global greenhouse gas (GHG) emissions. In some regions, the share of the total is even larger. For example in the Euro area it is around 15% (see chart below), and in Switzerland transportation is responsible for even more than 30% of the total GHG emissions.
The electrification of everything: opportunities in the decarbonisation of energy production and storage
This is the first post in a series on the opportunities presented by tackling climate change. In this article we cover renewable energy production and storage. Future articles will address transportation, food, etc.
An amazing future - climate action as an opportunity
As we enter the new decade, looking back climate change is probably the dominating topic of 2019. And rightfully so: a sense of urgency and swift action are needed! However, when it comes to the discussion around efforts to decrease the world’s greenhouse gas emissions, my concern is, that too much emphasis is put on the challenges. Instead, we should focus on the opportunities!
